For Better Performance: Headers or LSD?
I just had the K1 mod done today. It was raining, so I can't feel the difference yet. If I wanted to take the next step, but only one step, which would get me better speed off the line and performance for light to light racing, headers or LSD?

I will go against the grain here and say headers. We are already pulling 1.8's and 1.9's out of the hole bone stock. That says that you are getting plenty of your power down. Even assuming that you could shave a tenth off of that with LSD, once you are out of first gear, the LSD doesn't really do anything for you. Headers, on the other hand, will always show their value.
Now - if you CAN'T put the power down with the K1, then it is a different story.

For having fun around town I would say headers and pulley, for track sounds like the LSD might be a good start.

I'd say neither. Best bang for the buck IMO are a set of DR's. Spend less than a grand and you'll cut more off your time than either of the other two things. Then, get the headers and then the LSD.
..........which drag radials do you use? Do you have drag radials in all four wheels or just in the rear wheels? what tires sizes. Thanks.

I want to shave time off 0-60 to pass vettes and porshes during everyday driving. If drag slicks are not part of the plan, headers or LSD?

Your car stock will pass most vettes and porsches. With K2 you will destroy most. Your car will be running 0-60 in under 4s and 1/4 times in the mid 11's.
Enjoy

If you're just driving down the street I'd still get both but would start with the headers. I had the headers and then the LSD. While the LSD helps, it was not as impressive of a mod as the K2 was. I doubt you'll be running mid 11's but you might. My best was 11.65 with K2, LSD, and DR's. Usually it was in the upper 11.7's to 11.8's.
I run the BF DR's only on the rears with a 275 tire size. I pump the fronts up to about 45 psi. I'm looking for a cool, hopefully MB, 17 inch rim that will fit our cars so I can run the MT SR's which are suppose to be even stickier.

Does Kleeman charge for another computer upgrade when you put on headers or is it just the price of headers plus install? Do you even have to send the computer back in after the headers go on?

M2 - they think my 0-60 time and 1/4 mile time will be most affected w/ LSD. What say you? (BTW- they brag that they will have you in the 10's in no time!)

LOL, they seem to be really cool guys. They haven't done any work on my car but they do have some good ideas. I'm workin' on it.
Is this the FINAL mod or are you going to do one then another? Is it going to be 12 months before you can do the next step or 3 months? In the end, I'd probably defer to my tuner's advice and then get everything when you can get it done.
I wish I had done DR's and LSD before I did K2. I did NOT break into the 11's with K2. That did not happen until I had the LSD and the DR's. It's kinda like the criticism of the 600's and the 65's- you can have all the HP in the world but if you can't properly get it to the pavement, then it doesn't matter.

I would like to only have one more mod and do it w/in the next 3 - 6 mos (have to get the wife used to the idea). If you had to chose only one more mod - which would it be? Am I to understand your performance increasedt he most w/ LSD as opposed to headers?

What was your baseline dyno and then the dyno after the K1 install?

Max at the wheel was 404.83hp and 424.45 ft-lbs 84.38 degrees 29.97 in-Hg before K1. I have to get after dyno next week - they had a 1200 Hp Viper on the machine and I couldn't wait around for them to finish.
